Opinion

UNITED STATES DISTRICT COURT AT SEATTLE CITY OF TACOMA, CASE NO. 2:24-cv-99 Plaintiff, ORDER ON CROSS-MOTIONS FOR v. WESTERN METAL INDUSTRY PENSION FUND and its BOARD OF TRUSTEES, Defendants.

1. INTRODUCTION An employer who withdraws from an underfunded multiemployer pension plan must pay its fair share of the plan’s unfunded liabilities. Congress established this “withdrawal liability” as a fixed debt owed to the pension plan when it passed the Multiemployer Pension Plan Amendments Act of 1980. See Pension Ben. Guar. Corp. v. R.A. Gray & Co., 467 U.S. 717, 724–5 (1984); 29 U.S.C. §§ 1381, 1391. This case arises from an arbitration award concerning Plaintiff City of Tacoma’s (“the City”) withdrawal liability to Defendant Western Metal Industry Pension Fund (“the Plan”). An arbitrator has already ruled that the Plan improperly calculated the City’s liability by using interest rates that didn’t reflect the Plan’s actual investment experience. The parties now seek judicial review of

that arbitration decision. At issue is whether the Plan’s actuary made appropriate assumptions when calculating the City’s withdrawal liability. ERISA requires plan actuaries to use reasonable assumptions that “tak[e] into account the experience of the plan and reasonable expectations” of investment returns and “offer the actuary’s best estimate of anticipated experience under the plan[.]” 29 U.S.C. § 1393(a)(1). The

Plan’s actuary, however, did not base her interest-rate assumptions on the Plan’s actual or expected investment returns of 7%. Instead, she used significantly lower “settlement rates” prescribed by the Pension Benefit Guaranty Corporation (“PBGC”) for terminating plans—between 2.53% and 2.84%—ratcheting up the City’s assessed liability by about $30 million. Having reviewed the record, the parties’ briefing, and the law, the Court, being fully informed, GRANTS the City’s motion to enforce the arbitrator’s award,

Dkt. No. 17, DENIES the Plan’s motion to vacate, Dkt. No. 18, and confirms the arbitrator’s order requiring the Plan to recalculate the City’s withdrawal liability using a 7% interest-rate assumption. Binding Ninth Circuit precedent clearly prohibits plans from using PBGC settlement rates that ignore the plan’s actual investment experience. The arbitrator correctly applied this law to the undisputed facts.

2. BACKGROUND 2.1 Legal background. Congress enacted the Employee Retirement Income Security Act of 1974 (ERISA) “to provide comprehensive regulation for private pension plans.” Connolly v. Pension Ben. Guar. Corp., 475 U.S. 211, 213 (1986). ERISA aims “to ensure that employees and their beneficiaries would not be deprived of anticipated retirement benefits by the termination of pension plans before sufficient funds have been accumulated in the plans.” Gray, 467 U.S. at 720 (citing Nachman Corp. v. Pension Ben. Guar. Corp., 446 U.S. 359, 361–362 (1980)). To achieve this goal, Congress “created the Pension Benefit Guaranty Corporation (PBGC), a wholly owned Government corporation, to administer an insurance program for participants in … pension plans.” Connolly, 475 U.S. at 214; see 29 U.S.C. § 1302. To address financial instability in multiemployer pension plans, Congress later passed the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA), which requires employers who withdraw from such plans to pay “withdrawal liability”—their “proportionate share of the plan’s unfunded vested benefits.” Gray, 467 U.S. at 717, 725; 29 U.S.C. §§ 1381, 1391. Central to this case is how withdrawal liability is calculated. When an employer withdraws, the plan’s actuary determines the liability amount by applying various “actuarial assumptions,” with the interest-rate assumption being “arguably the most important.” Concrete Pipe & Prods. of Cal., Inc. v. Constr. Laborers Pension Tr. for S. Cal., 508 U.S. 602, 633 (1993). A higher interest rate yields higher projected growth, reducing the liability assessment; a lower rate increases the liability assessment. GCIU-Emp. Ret. Fund v. MNG Enters., Inc., 51 F.4th 1092,

1099 (9th Cir. 2022). ERISA requires that these actuarial assumptions be “reasonable (taking into account the experience of the plan and reasonable expectations)” and, “in combination, offer the actuary’s best estimate of anticipated experience under the plan[.]” 29 U.S.C. § 1393(a)(1). Alternatively, the statute also permits the use of actuarial assumptions derived from PBGC regulations (see 29 U.S.C. § 1393(a)(2)),

but because no such final regulations have been issued, plans must currently use the first method. See GCIU, 51 F.4th at 1098 n.2. Importantly, the legal framework for individual employer withdrawals differs from that governing mass withdrawals when all employers exit and the plan is terminated. In mass-withdrawal situations, plans must typically purchase annuities to cover benefits, and PBGC prescribes settlement rates reflecting risk- free annuity prices rather than expected investment returns. See Sofco Erectors,

Inc. v. Trs. of Ohio Operating Eng’rs Pension Fund, 15 F.4th 407, 420–21 (6th Cir. 2021). The MPPAA also establishes procedures for employers to challenge withdrawal-liability assessments. Once the plan determines the liability amount, it issues a notification and demand to the employer. 29 U.S.C. § 1399(b). If the employer objects, the matter proceeds to mandatory arbitration. 29 U.S.C. §

1401(a)(1). During arbitration, the plan’s calculations are presumed correct unless the employer shows by a preponderance of evidence that “the actuarial assumptions and methods used in the determination were, in the aggregate, unreasonable” or “the plan’s actuary made a significant error.” 29 U.S.C. § 1401(a)(3)(B).
